REPROCESSING OF REFLECTION SEISMIC DATA FROM THE SKÅNE AREA, SOUTHERN SWEDEN

Abstract: Numerous seismic reflection profiles have been acquired both on and offshore in southern Sweden for the purposes of petroleum exploration. No producing fields were discovered in the area, but the data comprise an important scientific asset. They may even prove valuable in the future for purposes such as non-conventional energy storage and production and sequestration. Most of these data were processed using software from the 1970s. This report covers all steps necessary to understand and produce final section for 2-D seismic line, the theory part give the reader brief background about seismic data processing methods, the concepts of deconvolution , F-K filter , digital filters , correction , stack and migration are discuss in this part of the report. Processing gather start with input SEG-Y formatted shot gathers, and then followed by amplitude correction, mute, frequency filtering, F-K Filtering, deconvolution, velocity analysis, NMO correction, stack, migration and view the 2-D slits in 3-D coordinate display. Comparison between the two results the one from 1970s and the new one produced by Claritas (software use to process seismic data) show that new results are more enhance and accurate which improve the geological interpretation result and make it more accurate .
